SHUTTLE-MOTION FOR LOOMS.

isi-ECIFICATION forming part of Letters Patent No. 312,680, dated February 24, 1885.

' Application filed September 3, 1393. (No model.)

in looms of various kinds, it is especiallyim tended for use in what are known as narrow-Ware7 looms for weaving narrow fabrics.

The invention vrelates to that class of looms in which are employed shuttle-carriers having hinged sides, which are arranged to reciprocate in raceways on opposite sides of the loom and to advance into. the warp in oppof site directions, one of which shuttlecarriers carries the shuttle partly through the warp and delivers it to the other carrier, which, as it retires, takes the shuttle the remaining distance through the warp.

The invention consists in a novel and simple combination of mechanism,hereinafter described, for reciprocating the shuttle-carriers, whereby there is obtained at the end of the movement of the shuttle-carriers outward or away from each other a dwell of sufficient duration to enable the lay to beat up and retire. l

The invention also consists in a novel combination of mechanism, particularly hereinafter described, for operating the hinged sides of the shuttle-carriers,to engage them with and to disengage them from their shuttle.

`In the accompanying drawings, Figure l is a plan of a portion of a loom embodying my invention. Fig. 2 is a sectional elevation thereof and Fi g. 3 is a transverse vertical section on the plane of the dotted line :v x, Figs. 1 and 2.

Similar letters o'f reference desi gnatecorrespending parts in all the gures.

A designates the top plate of the loom, and A are the end frames supporting the same.

B designates the raceways, arranged in line, and having between them an opening, B, for the shed and the beating up ot' the lay. In these raceways are shuttle-carriers C, capable of being reciprocat-ed therein simultaneously toward andfrom each other and serving to motion from a main shaft, E, by bevel-wheels' F. The main shaft may be rotated by a belt over a pulley, El, partly shown in dotted outline in Fig. 2, and said shaft has its bearings in brackets d, which also contain the lower bearings, c, for the shafts E.

On the under sides of the shuttle-carriers C are downwardly-pro] ecting studs e; and Gdesigates levers which are fulcrumed at e' at one end, so as to swing in a horizontal plane, and at the other endsof which are forks e", embracing the studs or pins e. One side of each fork is made separate from the lever, and may` be tightened by a screw, es, to take up wear between the stud and its `embracing-fork.

On the upper end of each vertical shaft E is a crank, E', and the crank-pin f of each crank is connected by a link or oonnecting1od, G', with the corresponding lever, G, between its ends. The lever G, at the right-hand end of Fig. l, is shown dotted in two positions, in order to more clearly illustrate its movements.` The peculiarity in the connectingnod is that its length is less than the throw or stroke of the crank, and but very little more than the length of the crank from the center of the shaft E to the center of the crank-pin f. The result of this particular length of crank is that at the outer end of the movement of the shuttle-carrier C a dwell of considerable length will be a'orded, giving the lay ample opportunity to beatV up and retire.

I do not claim, broadly, as of my invention the combination of a lever, a crank, and a connecting-rod for operating the shuttle-carrier, and desire to cover such combination only when the connecting-rod is of substantially the dimension stated.

I will now describe the mechanism whereby the hinged sides b of the shuttle-carriers are engaged with and disengaged from the shuttle D; but I would here remark that by the term hinged sides,77 as herein used, I desire to cover movable sides, whether they are hinged by pivots, as shown, or are hinged by flexible portions or springs.

On the under side ofthe table or top plate, A, is a frame or plate, H, which is adapted to slide for a short distance horizontally, and which is guided by slot-s g in it fitting studs g on the top plate, A, as shown dotted in Fig. l.

The frame or plate H comprises two straight portions, H, which are adjacent to the raceways B, and a connecting yoke or portion, H', which connects said straight portions, and is out of line with them, so as to leave clear the opening or space B for the movement of the lay and shed. In the straight portions of the frame or plate H are slots h, which receive pins h', projecting downward from the hinged sides b ot` the shuttle-carriers C', and at the ends ofthese slots are cam-like portions or continuations h2 thereof.

In order that the pins h on the sides b of the shuttle-carriers C shall stand in proper rel-ation to the cam-like portions lr ofthe slots at the end of the inward movement of the shutv tie-carriers, or when they are nearest together, I divide the yoke II of the plate H and connect the two portions by bolts and slots h", as shown in Figs. l and 2. The two portions of said plate or frame H may then be adjusted and held securely in proper relative position.

In 'order to release vthe hinged sides b of the shuttle-carriers from the shuttle, I move the'plate or frame H slightlyvin the direction of the movement of the shuttle-carrier, andl thus cause the cam-like slot'portions ha to act on the pins h', and thus to move the hinged side of one shuttle-carrier in'to engagement with vthe shuttle, and remove the hinged side of the other shuttle-carrier from the shuttle. In the present example of my invention I effect this movement in the following manner: Y

I designates a lever fulcrumed at z', and connected at one end, i', with the left-hand end of t-he plate or frame H. At its opposite end this lever carries a roller or bowl,

The lever I here shown consists of a rockshaft and two arms, asv shown in Fig. 3.

Onthe uprightshai't E, at the left-hand end of the loom, Figs. l and 2, is loosely mounted 'a bevel-wheel, J 5 and J designates a bevel-pinion fixed on the main shaft F, and imparting to the wheel J a rotary motion independent of the shaft E. In the upper side ofthe wheel J is a cam course or groove, j, in which iits the 'roller or bowl i2 on the lever I.

The wheel J and pinion J are of such size that the wheelJ only makes one revolution to each two revolutions of the shaft E. The effect of this combination is that at vthe termination of each inward movement of the shuttle-carriers C, and when they are in the position shown in Fig. l, the plate or frame H is moved slightly,and the hinged side b of one carrier is moved away from the shuttle D, while that of the other carrier is moved toward and engaged with the shuttle, and the shuttle is thus grasped alternately by each carrier and released from the other carrier.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination, with a shuttle-carrier, C, of a lever, G, fulcruined at one end, e', and connected at the other end with the carrier, a crank, E', and means for rotating it, and a connecting-rod, G,the length -ot` which is less thanv the throw or stroke ot' the crank, and which forms a direct and inflexible connection between the crank-pin and said lever G between its ends, substantially as herein described.

2. Thev combination, wit-h the forked shuttleAcarriers C, each having a hinged side, b, provided with a pin, h, and mechanism for reciprocating said carriers,- oi' the plate or frame H, arranged approximately parallel with the line of movement of said shuttle-carriers, and provided with canrslots h h2, receiving the pins h', means for reciprocating said plate or frame to alternately engage and release the hinged sides of said shuttle-carriers with and from a shuttle, and guides for said recipreciprocating said plate or frame, to alternately engage and release the hinged sides of said shuttle-carriers with and'from a shuttle, and guides for said reciprocating plate or frame, substantially as herein described.
